宾语,位于谓语动词或者介词后。
从句在复合句中作宾语的名词性从句，通常放在主句谓语动词（及物动词）或介词之后。 eg. We knw Mr Green teaches English. She asked if these answers were right.
引导词（连接词）语 序时 态
不同引导词引导的宾语从句
由从属连词 that 引导的宾语从句
由连接代词 Wh,whm,whse,which,what 和连接副词 where,hw,why,when引导的宾语从句
由从属连词 whether, if 引导的宾语从句
e.g. I hear (that) _______________________. He said (that) ______________________. The teacher tld us (that) _______________ ________________.
he will be back in an hur
he missed us very much
the earth mves
1.由从属连词 that 引导的宾语从句
注：that 引导的从句，表示陈述一件事实，主句谓语动词表示确定，不疑问；that在句中无任何意义，不充当句子成分，常省略。
arund the sun
2.由从属连词 whether, if 引导的宾语从句
I want t knw _______________________ _______________.2. Ask him _________________________. 3. I wnder ____________________________.4. Culd yu tell me________________________ ?
if (whether) he will g t the park with us
whether (if) he can cme
whether it is ging t rain r nt
if/ whether “是否”，说明对陈述的事物不明确或不清楚。常用在ask, wnder, can(culd) yu tell me 表示疑问不确定意义的词之后；从句句意完整，不缺成分。
whether(if) Mr Li lives here
1. 在引导主语从句、表语从句时如：　⑴Whether it is true remains a questin.　⑵The questin is whether it is true. 2. 用在动词不定式之前时用whether不用if。　I dn’t knw whether t g there at nce. 3.当与r nt连用，或 r 提出两种选择时:I dn’t knw whether he’s free r nt.Mary asked whether I was ding my hmewrk r nt.Tell me whether yu’d like t g shpping r tidy the rm.
注意：只能用 whether不能用 if 的情况 1
注意：只能用 whether不能用 if 的情况 2
4. 在介词或dicuss后面：I’m thinking f whether we shuld g fishing.We discussed whether we shuld clse the shp.5. 与动词不定式连用(whether t d sth.) ：They asked me whether t g skating.6. 为了强调宾语部分，也可把从句提在主句前。　　 Whether he will cme I am nt sure.
注意：只能用if 不能用 whether的情况
1.引导条件状语从句If he runs fast, he’ll get there n time. I’ll g t see yu if I have time.2.引导否定的宾语从句Tell me if it is nt ging t rain, please.
if whether用法巧记
两个“是否”并不难，一般情况可代换。下列情况用whether, 主表不定式r (nt)。作为讨论介词宾， 此时 if 不可跟。还有一点也得编， whether从句可提前。引导条件表“如果”，再也不可用whether。宾语从句若否定， whether一词不可用。
Practice time
选择 if / whether。1. I asked her __________ she had a bike.2. We’re wrried abut ________ he is safe.3. I wnder ___________ he is well.4. I dn’t knw ________ r nt he is well.5. I dn’t knw _______ t g.
if / whether
whether /if
1. He asked _____________________________. 2. D yu knw_________________________?3. He asked_______________________________.
wh culd answer the questin
whm they are waiting fr
whse bike was the best in the class
由连接代词 Wh,whm,whse,which,what 引导的宾语从句
主句谓语动词，表示疑问不确定含义，要用疑问代词引导宾语从句，并在从句中担任句子成分，具有一定的意义，不可省略。
连接副词 where,hw,why,when 引导的宾语从句
1.D yu knw ________________________?2. Please tell me _____________. 3.Can yu tell me ____________________ ?4.Culd yu tell me ____________________?
主句谓语动词，表示疑问不确定含义，要用疑问引导宾语从句，并在从句中担任句子成分，具有一定的意义，不可省略。
when we’ll have a meeting
where he is
hw I can get t the statin
why the train is late
二、语序宾语从句的语序用陈述语序：连接词+主语+谓语+其他成分
1. When will he g t the library? His brther asks when he will g t the library .
2. What did he want t buy ? I dn’t knw what he wanted t buy .
主句+连接词+从句（主+谓+其他成分）即：助动词不能放在主语前面。
What’s wrng? What’s the matter? What’s happening? Wh is ver there？
注：当从句的原句为以下句子 以及what, wh作主语时，语序不变：
eg: I dn’t knw what’s the matter.Can yu tell me wh is ver there?Can yu tell me wh he is ?
若主句谓语动词为think, guess，imagine，suppse,believe等其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式；其反意疑问句，疑问从句。
否定前移及反意疑问句形式巧记法
I dn't think this dress fits yu well, des it? 我认为这件衣服不适合你穿,是吗？I dn't think yu are right，are yu?我认为你是错的,是吗？I dn't believe yu will finish the wrk tday， will yu?我认为你今天无法完成工作, 是吗？
我认为猜想有假不可信，提问宾从构反问。从句若表否定意， 否定词语要前移。
I knw he lives here .I knw he lived here ten years ag . I have heard that he will cme tmrrw .
主句用现在时或将来时，从句可用任何时态，根据实际情况而定。
2.如果主句是过去的时态（一般过去时，过去进行时），从句的时态一定要用相对应的过去的某种时态（一般过去时，过去进行时，过去将来时，过去完成时）
I knew wh lived there. I saw she was talking with her mther. He asked whether his father wuld cme back the next day. He said that he had seen the mvie .
3. 从句说明的是一般真理、客观事实、自然 现象时，仍用一般现在时。
Dad tld us that it is better t d than t say.He tld the by that three and three is six.He tld me the earth mves arund the sun.Mr. Li tld me the sun rises in the east.
1. The radi says it _______ cludy tmrrw. (be)2. The headmaster hpes everything ______ well. (g)3. I hear they __________ (return) it already. 4. He said that they _________ members f the Party since 1948. (be)5. Our teacher tld us in class the sun _______ in the east. (rise)
have returned
宾语从句要注意，时态引导词和语序。
时态问题看主句，现在时态可随意。过去时态用过去，客观情况要注意，主过从现要切记。
引导词 , 并不难，主句含义最关键。主表肯定意完整，that常用也可省。主表疑问不确定，另类词, 要使用。从句句意若完整，if/wether不可省。从句若是缺成分，特殊疑问词来过问。
还有一项是语序，陈述语序要切记。如何对它来判断，助动莫放主语前
